Failure to provide installation documents from repair facility. (Self/parking lot installs)
Failure to perform and document scheduled maintenance on time.
Seaping/leaking oil out of compression outlet, caused by excesive BLOW BY or clogged crankcase FILTER.
Failures due to Improper installation or maintenance, restricted oil feed pipe, damaged oil pump, low oil level, metal particles or carbon present, faulty DPF filters and/or EGR valves, contaminated lubricant, oil starvation.
Using liquid gasket or sealing compounds
White deposit present on exhaust parts due to excessive engine oil burn.
Over speeding, defective intercooler and or compression piping, stuck VGT, Remap
Foreign object and physical damage, defective or dirty air filter and supply pipes.

Due to the intricacies involved in warranty process and the industry standard protocol regarding the inspection of parts and turnaround time, we will not offer free replacements prior to full inspection and analysis.

Installation tips

Most common misdiagnosis.

Oil leaks can be caused by a variety of factors, the main factor being incorrect pressure within the compressor and turbine housings, which is usually caused by:

Blockages to the air intake filter and/or hoses.
Excessive crank case pressure (blow-by from worn piston rings/bores)
Blockages in the exhaust system
Repeated hot engine shutdowns leading to carbon deposits (coke) in the centre housing
Dirty crankcase filter
Use of silicon sealant / incorrect gasket, twisted, bent or trapped oil return pipe

Most common turbocharger failure causes on semi trucks:

Foreign object damage – Broken off engine components, e.g. valves (D13), fragments of damaged pistons or injector tips, EGR block off plates.
Oil contamination – High carbon build up present in the engine can quickly contaminate new oil, contamination of new oil while servicing.
Degrading oil – excessive temperatures or extended service intervals.
Internal engine leaks – fuel or coolant mixing with oil supply.
Turbocharger overspeeding – Engine modifications including ‘chipping’ or ‘over-fuelling, bad program installed if EGR/DPF delete was performed, worn injectors. Tear in the air hose or the hose becoming completely detached. Restrictions in the air intake filter or pipe work. Air leaks between compressor and engine.
Lack of lubrication –

1. Engine left idle for long periods, especially during cold weather
2. Oil feed pipes containing bends or kinks
3. Lack of maintenance, oil change intervals should be shortened as engine gets old.
4. Insufficient oil in the sump
5. Incorrect oil inlet gasket used leading to restriction in oil supply
6. Build-up (coking) / carbon deposits in the oil feed pipe
7. Applying silicone to the oil inlet gasket causing blockages
8. Sludge or coke build up in bearing housing from hot shutdowns
9. Failure to prime the turbo with oil before initial run
